State department announces goals for Blinken's Mexico trip, "Secretary Blinken will discuss irregular migration in the Western Hemisphere and identify ways Mexico and the United States will address border security challenges including actions to enable the reopening of key ports of entry across our shared border".

Well it is about time, I know when I think of the tsunami of fake asylum seekers gaming the system, the conclusion I come to is that we need get all the entry points open and flowing in as fast as our treasury will allow for and open for as many years as it takes to drain the entire world of people who choose to come here.

I think you're misunderstanding the specific context of that quote.

As we've discussed, there aren't a whole lot of levers available for the U.S. Administration to stop migrants from requesting asylum. We can't physically prevent them from reaching U.S. territory, and once they're physically in the U.S. they can make an asylum claim. But Mexico can take steps to stop them from reaching the U.S. border, since most of the asylees are traversing Mexico.

The U.S. recently has tried to play a little hardball with Mexico. We shut down a few ports of entry entirely, completely disrupting Mexican-U.S. industries in those areas. Ostensibly, the reason was because the Administration was "reallocating" border patrol/ICE/DHS to other parts of the border in order to address migration problems elsewhere. The U.S. is using the shutdown of those ports to try to pressure Mexico to step up enforcement along its own southern border (to stop migrants from entering Mexico down in Chiapas) and internally (for example, using domestic police to stop migrants from hitching rides north on freight trains).

That's the "reopening of key ports of entry" that Blinken is referring to. Not to facilitate movement of migrants, but the normal movement of industrial products and goods across the border that we've temporarily blocked to put pressure on AMLO to do things that Mexico doesn't want to do.
